If we get as far as calling libmagic, return the correct error code so
that mkfs asks for confirmation if libmagic finds something and
doesn't ask if nothing is found.

If magic.h is not present, there will be unresolved references to the magic_t
type in plausible.c. Fix that by moving the protecting #ifdef directive.

Move check_plausibility() into a separate file so that various
programs can use it without having to declare useless global variables
that the util.c functions seem to require.
